Nginx虚拟主机应用：(创建多个基于域名的虚拟主机并测试)

Posted 2020-11-14 cxm123123form

 

 

一：使用nginx搭建虚拟主机服务器时，每个虚拟WEB站点拥有独立的"server {}"配置段，各自监听的IP地址、端口号可以单独指定，当然网站名称也是不同的。

二：虚拟机的分类：

  1：基于域名虚拟主机（一个ip地址对应多个域名，不同域名就是不同的站点，其内容也不一样）

  2：基于端口虚拟主机（服务器只有一个ip地址，不同端口就是不同的站点，其内容也不一样）

  3：基于ip虚拟主机（服务器有多个ip地址，不同ip就是不同的站点，其内容也不一样）

Active connections 表示当前活跃的连接数，

第三行的三个数字表示Nginx当前总共处理了2个连接，成功创建3次握手，总共处理了2个请求。

要创建两个站点www.crushlinux.com和www.cloud.com

为两个虚拟WEB主机分别建立根目录，并准备测试首页

 

[root@localhost~]#mkdir /usr/local/nginx/html/crushlinux

 

[root@localhost~]#mkdir /usr/local/nginx/html/cloud

 

[root@localhost~]# echo "<h1>www.crushlinux.com</h1>" >/usr/local/nginx/html/crushlinux/index.html

[root@localhost~]# echo "<h1>www.cloud.com</h1>" > /usr/local/nginx/html/cloud/index.html

[root@localhost~]# vim /usr/local/nginx/conf/nginx.conf
